The indicater meter is a DC device, so the rectifier changes AC to DC.
A meter could not respond to AC.

What are the advantages and dis advantage of full-wave bridge rectifier compared with two diodes rectifier?
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.
What is the input output of rectifier?
Current flowing in only one direction.
What is the relationship of the input frequency and output frequency in a FULL-wave rectifier?
The frequency of a full-wave rectifier is double that of the input, if the input is a sine wave or triangle wave. If the input is a square wave, the output is DC. If the input is a sawtooth wave, the output is a triangle wave of the same frequency.
Does a Digital Voltmeter have a high or low input impedance?
Digital voltmeter has high input impedence.
What is internal impedence of digital multimeter?
A: [practically all commercial digital meter have a 11 mega ohm input impedance but there are special meters that can be used to measure leakage current and they have impedance high enough to measure nano amps. Even an oscilloscope will have these kinds of impedance such that the reading is not influenced by external loading
What is the function of a output terminal in an analog multimeter?
The purpose is to buffer the input for monitoring purposes
What is the principle of digital multimeter?
A: A VOM digital requires to have a ADC analogue to digital converter whereby the analogue input will be displayed as number representation. An analogue meter all it requires is to have is current flow through it.
What is the working principle of DMM?
a digital multimeter uses similar input circuits to those used in an analog multimeter for the various scales, but uses a dual slope integrating analog to digital converter to get a precise digital value of four or five digits to display. this type of analog to digital converter is slow but very precise, also though slow it is more than fast enough for a human to not perceive the slowness.
What is an input device used to measure variables?
multimeter
Does the bridge rectifier follow the value of the input current?
No.
What does the out put wave form looks in a rectifier?
A rectifier allows current to flow only in one direction. In a half-wave rectifier circuit, an input wave which oscillates between positive and negative, will 'pass through' the positive portion of the wave, and when the input is negative will output zero. A full-wave rectifier circuit, is commonly configured with 4 rectifier diodes, which allow a positive wave to output when the input wave is negative.
What is output frequency of bridge rectifier?
twice the input frequency
What is the lowest ripple frequency of half wave rectifier?
The ripple frequency of a half-wave rectifier is the same as the input frequency.
Which type of rectifier has the greatest output voltage for the same input voltage and trasformer turns ratio?
Bridge Rectifier
What are the advantages and dis advantage of full-wave bridge rectifier compared with two diodes rectifier?
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.
Digital pen an output or input?
digital pen is an input device
What is the input output of rectifier?
Current flowing in only one direction.
